Admittedly, it's not, the limit on the WV section of I-79 is 70mph, with one 65mph section...

Even worse, there were some downhill sections where I was cruising with traffic at around 90mph... Which makes the mileage I got pretty awesome... I also found that load based cruising on the interstate makes the car run cooler; I was contemplating opening my grille block further due to engine temps around 215F, but without allowing a downshift, temps were usually under 210F on hills, and around 195-200 on flat ground...

On the subject of speed, I have determined that while you can cruise past cops usually at around 10 over, they'll fry you at 12-15 over, hence the target speed...
